iHalo: used to render halos (aka "light globes").
This interface can be used as well for any scalable semi-transparent 2D sprites. The "halo" is really just an alpha map; the sprite is a single-colored rectangle with more or less transparent portions (depends on alpha map).

) | [pure virtual] |
Draw the halo given a center point and an intensity.
If either w and/or h is negative, the native width and/or height is used instead. If the halo should be clipped against some polygon, that polygon should be given, otherwise if a 0 pointer is passed, the halo is clipped just against screen bounds.
